A method and system of conferencing can include the steps of initiating a conference call at a communication device with two or more communication devices and selecting to suppress a voice communication of at least one communication device on the conference call where a modified electronic signal is generated with the selected at least one communication device so that the voice communication from the selected at least one communication device is inaudible. The method or system further includes sending the modified electronic signal to at least one other communication device on the conference call. Other embodiments are disclosed.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A first communication device, comprising: a memory that stores instructions; and a processor that executes the instructions to perform operations, the operations comprising: selecting to suppress a voice communication of a second communication device on a call with the first communication device; producing acoustic audio content based on audio content associated with the call that is delivered via an ear canal receiver of the first communication device; providing, by utilizing an ear canal microphone of the first communication device, an electronic internal signal based on the acoustic audio content to an adaptive filter coupled to a reference signal; and generating, by utilizing the adaptive filter, a modified electronic signal based on the electronic internal signal and the reference signal; and suppressing the voice communication of the second communication device in the modified electronic signal.
2. The first communication device of claim 1 , wherein the operations further comprise providing the modified electronic signal to a third communication device on the call after suppressing the voice communication in the modified electronic signal.
3. The first communication device of claim 1 , wherein the operations further comprise initiating a conference call using the first communication device, the second communication device, or a combination thereof.
4. The first communication device of claim 1 , wherein the operations further comprise enabling a conference call initiator to preselect a caller to suppress.
5. The first communication device of claim 1 , wherein the operations further comprise adjusting volume of the audio content to a predetermined level.
6. The first communication device of claim 1 , wherein the operations further comprise suppressing, by utilizing an echo suppressor, feedback associated with a spoken voice received from the ear canal receiver.
7. The first communication device of claim 1 , wherein the operations further comprise determining a background noise level of an environment associated with the first communication device.
8. The first communication device of claim 1 , wherein the operations further comprise mixing an audio signal captured at an ambient sound microphone of the first communication device with an audio signal captured at the ear canal microphone of the first communication device to produce a mixed signal.
9. The first communication device of claim 8 , wherein the operations further comprise providing the mixed signal to a voice recognition system, a voice dictation system, a voice recorder, or a combination thereof.
10. The first communication device of claim 8 , wherein the operations further comprise producing an echo estimate based on the electronic internal signal and the mixed signal.
11. A method, comprising: selecting to suppress a voice communication of a second communication device on a call with a first communication device; generating acoustic audio content based on audio content associated with the call that is delivered via an ear canal receiver of the first communication device; providing, by utilizing an ear canal microphone of the first communication device, an electronic internal signal based on the acoustic audio content to an adaptive filter coupled to a reference signal; and generating, by utilizing the adaptive filter, a modified electronic signal based on the electronic internal signal and the reference signal; and suppressing the voice communication of the second communication device in the modified electronic signal.
12. The method of claim 11 , further comprising modeling an ear canal transfer function by utilizing the adaptive filter.
13. The method of claim 11 , further comprising providing a voice associated with the call in the modified electronic signal.
14. The method of claim 11 , further comprising managing an echo feedback condition affecting a voice activity level determined in an environment associated with the first communication device.
15. The method of claim 11 , further comprising subtracting an echo estimate from the electronic internal signal to produce the modified electronic signal.
16. The method of claim 11 , further comprising further comprise suppressing feedback associated with a spoken voice received from the ear canal receiver.
17. The method of claim 11 , further comprising transmitting the modified electronic signal to a third communication device.
18. The method of claim 11 , further comprising preserving a spoken voice occurring during the call when generating the modified electronic signal.
19. The method of claim 11 , further comprising adapting a first set of filter coefficients of a Least Mean Squares filter to model an inner ear-canal microphone transfer function of a first user associated with the first communication device.
20. A first communication device, comprising: a memory that stores instructions; and a processor that executes the instructions to perform operations, the operations comprising: producing acoustic audio content based on audio content associated with a call that is delivered via an ear canal receiver of a first communication device on a call with a second communication device; providing, by utilizing an ear canal microphone of the first communication device, an electronic internal signal based on the acoustic audio content to an adaptive filter coupled to a reference signal; and generating, by utilizing the adaptive filter, a modified electronic signal based on the electronic internal signal and the reference signal; and suppressing a voice communication of the second communication device in the modified electronic signal.
